To optimally analyze the given dataset, we started by searching information and collecting research from universities, institutions and organizations with experience in cardiology.
Then we proceeded to apply the knowledge acquired in analyzing the dataset and looking for possible combinations that bring new information to improve the prediction of cardiac events.
First of all we decided to get some metrics in terms of the dataset. We wanted to know the basic things that we needed in order to start analyzing the given data.
Graphs showing the percentages of men and women from the sample and their average ages where key to gain a basic understanding of what we were going to deal with.
According to research from DR. Enresto Delgado Cidranes in Peligros de la Angioplastia patients who are over 70 years old have a higher risk during procedure
After curating the dataset, a deep analysis was made in the search for connections between the variables which led to more complete queries.
The variables considered to be presented by graphs were: Tiempo de Bomba, Complicaciones Inmediatas, Complicaciones Tardias, vasos Angioplastiados
In the following graph the reason for admission is explored. This graph informs us about the most common problems which led to patients being hospitalized.
Patients between 55 and 72 years old are more prone to needing an external pump during procedure. It was decided that analyzing the amount of time a patient had the pump, tied to their age could give more insight to the problems related to this. The paper Complicaciones quirurgicas gives a more in depth perspective of why older patients tend to need more time with an artificial source of pumping. Cardiac surgeries with extracorporeal circulation also increase the risk of complications as they are aggressive interventions with manipulation and lung collapse during surgery
;
In conclusion, it was found that what was stated in the paper mentioned above also applied to the Hospital Austral Dataset. Patients between the mid fifties and low seventies tend to use an external pump during surgery. This lowers the risk of failure in a risky procedure such as this.
Age plays an important role at the time of complications during and after surgery.
A higher number of angioplasted vessels means lower success rate. 87% for 1 vessel, 80% for 2 vessels and 69% for 3.
The analysis of the dataset led to
